When will you finish your school.? what are your favourite subjects.?

I will graduate from my high school by the age of nineteen, just like the typical teenager in America would do. I enjoy a variety of subjects in my high school, but my favorite one is certainly Economics as I find it a good fit for my future career. I personally like learning about different types of economic systems and policies and the enormous effect it can have on the people from not only the United States but also the rest of the world. Also, I feel like its a good idea to cover Economics before eventually starting a business, which I might do in the future.
